In this case, the case 110 is mounted in the syringe drive unit 130, the control unit 140, and the battery 150, and forms the frame of the automatic drug solution injecting apparatus of the present invention.

The case 110 forms the frame of the automatic drug solution injecting apparatus of the present invention. The case 110 is formed in a cylindrical shape or a polygonal shape (for example, a square, a pentagon, etc.) And the total length is preferably 10 cm to 20 cm for miniaturization.

The syringe 120 is removably coupled to the front of the case 110. The syringe 120 includes an ampule 124 filled with a chemical solution, a needle 122 coupled to one side of the ampule 124 and injected into the body of the subject, And a piston 126 which is connected to the other side of the ampule 124 and presses the chemical solution in the ampule 124.

The injector 120 injects the chemical solution filled in the ampule 124 into the recipient's body through the needle 122 when the piston 126 is moved in the forward direction, The blood in the subject's body flows into the inside of the ampule 124 or the air flows into the inside of the ampule 124. As a result,

The syringe drive unit 130 is installed in the case 110 disposed at the rear end of the syringe 120 and is installed at a front end of the syringe 120 according to a control signal provided by the control unit 140. [ The syringe 120 is linearly moved in the forward and backward directions so that the needle 122 is injected under the subject and the piston 126 provided at the rear end of the syringe 120 is linearly moved in the forward and backward directions.

The syringe driving unit 130 includes a syringe pressing unit 132 for linearly moving the syringe 120 in the anteroposterior direction so that the needle 122 installed at the front end of the syringe 120 is injected under the subject, A piston pushing unit (not shown) for linearly moving the piston 126 in the anteroposterior direction so that the drug solution filled in the ampule 124 is injected into the recipient's body at a predetermined amount of the injected drug solution and the infusion rate after the injector 122 is injected into the recipient's body 134 and a pressure supply unit 136 that provides pressure to the syringe pressurizing unit 132 and the piston pressurizing unit 134.

The syringe drive unit 130 is configured to cause the syringe pressurization unit 132 to press the piston 126 after the syringe pressurization unit 132 has injected the needle 122 into the recipient's body. ) And the piston pushing unit 134 can be sequentially driven or the syringe pushing unit 132 and the piston pushing unit 134 can be simultaneously driven. In order to prevent the chemical liquid from being injected out of the in- It is preferable to sequentially drive the unit 132 and the piston pressing unit 134 (i.e., drive the piston pressing unit 134 after driving the syringe pressing unit 132).

When the pressure supply unit 136 is constituted by a linear motor, the pressure supply unit 136 may include a syringe pressurizing unit 132 and a piston pressurization unit 134 Can be directly coupled to the pressure supply unit 136. When the pressure supply unit 136 rotates in the same manner as the step motor, it is possible to convert the rotational force into a linear pressing force like the worm gear It is preferable that a means is provided between the syringe pressurizing unit 132 and the pressure supply unit 136 and between the piston pressurization unit 134 and the pressure supply unit 136, respectively.

The pressure supply unit 136 is configured to inject the chemical solution filled in the ampule 124 of the syringe 120 into the body of the subject after the needle of the syringe 120 is injected under the subject. The piston urging unit 134 is operatively coupled to the syringe pressurizing unit 132 and the piston pressurizing unit 134 after the piston 132 has operated.

The control means 140 is installed inside the case 110 and not only allows the user to set the injection amount and the injection rate of the chemical liquid but also controls the syringe drive unit 130 according to the set injection amount and the injection rate, A first communication unit 141 for receiving a signal transmitted from the foot switch 200 and a second communication unit 141 for controlling the operation of the foot switch 200 by exposing the outer surface of the case 110 so that the user can set the injection amount and the injection speed of the chemical liquid. A substrate 143 installed in the case 110 for controlling the operation of the syringe driving unit 130 according to an operation signal received by the first communication unit 141, And a display unit 144 electrically connected to the display unit 143 and exposed to the outer surface of the case 110 so as to display information such as the amount of the chemical solution injected, the injection rate, and the remaining amount of the battery.

The controller 140 controls the amount of the chemical liquid injected by the user to use the automatic liquid injector 100 even if at least one of the foot switch 200 and the first communication unit 141 fails, An operation button 145 for generating an operation signal to operate the syringe drive unit 130 according to the speed and a holding button 146 for controlling whether the operation button 145 is operated.

The operation button 145 and the holding button 146 are preferably exposed to the outer surface of the case 110 so that the user can press the operation button 145 and the holding button 146, Are preferably arranged in directions opposite to each other for division.

In general, the control unit 140 controls the operation of the syringe drive unit 130 only by an operation signal transmitted from the foot switch 200. However, as described above, When the operation button 145 and the holding button 146 are provided to the syringe driving unit 130 and the syringe driving unit 130 according to an operation signal input from any one of the footswitch 200 and the operation button 145, ).

In other words, when the holding button 146 is maintained in the off state, the control unit 140 controls the operation of the syringe driving unit 130 only by the operation signal input from the foot switch 200, The communication unit 141 and the substrate 143 are electrically connected and the operation button 145 and the substrate 143 are electrically disconnected.

The substrate 143 receives the operation signal transmitted from the foot switch 200 through the first communication unit 141 and the syringe drive unit 130 is moved forward according to the operation signal The chemical solution is injected into the body of the subject according to the set injection amount and the injection rate.

When the holding button 146 is changed from the off state to the on state, the control unit 140 controls the syringe driving unit 140 in response to the operation signal input from the operation button 145 provided on the outer surface of the case 110, The first communication unit 141 and the substrate 143 are electrically disconnected so that the operation of the unit 130 is controlled and the operation button 145 and the substrate 143 are electrically connected.

Accordingly, the substrate 143 receives the operation signal input from the operation button 145, moves the syringe drive unit 130 forward according to the operation signal, It is injected into the body of the recipient.

The first communication unit 141 and the operation button 145 are electrically connected to the board 143 so that the first communication unit 141 and the operation button 145 are electrically connected to each other, When the operation signal transmitted from the switch 200 and the operation signal input from the operation button 145 are all transmitted to the substrate 143 (i.e., an error occurs in the product or a failure occurs), the substrate 143 The display unit 144 controls the display unit 144 to display error information and controls the operation of the syringe driving unit 130 so that the syringe driving unit 130 does not move.

In other words, the control unit 140 can prevent the first communication unit 141 and the operation button 145 from being electrically connected to the substrate 143 due to water infiltration toward the substrate 143, When the connection is established, error information is displayed on the display unit 144 and the operation of the automatic chemical solution injection unit 100 is stopped.

Meanwhile, the operation mode set by the setting button 142 is a Dose mode and a Continue mode. The Dose mode is a mode used for injecting a drug solution of a predetermined injection amount. The Continue mode is a mode in which the user presses the foot switch 200 ) Or the operation button 145 is pressed.

The user (or the operator) can select the capacity (for example, 1cc, 1.5cc, 2.5cc, or 5cc) of the syringe to be used by the setting button 142 and set the set injection amount at a slow speed, The injection rate can be set to a desired unit (for example, 0.001 cc or 5 cc or the like).

For example, if there is a 1cc dose syringe 120 filled with 1cc of drug in the ampule 124, if the amount of injection once injected by the user through the setting button 142 is set to 0.1cc, If the injection amount is set to 0.01 cc, a total of 100 injections can be made. If the number of injections is set to 50, the amount injected at one time is automatically set to 0.02 cc.

The battery 150 is installed in the case 110 and supplies power to the syringe drive unit 130 and the control unit 140 for operation of the syringe drive unit 130 and the control unit 140 . The battery 150 may be used in both disposable and rechargeable types. When the battery 150 is formed as a rechargeable battery, a charging cable (not shown) for charging the battery 150 may be in contact with the rechargeable battery 150.

The foot switch 200 generates an operation signal to operate the syringe drive unit 130 according to a set amount of drug solution and a set injection rate. The foot switch 200 is disposed at a position where a user's foot is positioned, To the control means (140).

To this end, the foot switch 200 includes a button unit 202 for generating an operation signal for controlling the operation of the automatic chemical solution injecting means 100, an operation signal generated by the button unit 202, And a power supply unit 206 for supplying power to the button unit 202 and the second communication unit 204. [

The second communication unit 204 may be connected to the first communication unit 141 installed in the control unit 140 in a wired or wireless manner. However, in order to facilitate the use of the automatic chemical solution injection unit 100, The power source unit 206 may be connected to the first communication unit 141 through any one of a wireless communication scheme such as WiFi, Zigbee, infrared communication, and Bluetooth. , A rechargeable battery, and a power cable.

The overall operation of the automatic chemical liquid injecting apparatus having such a structure will be described below.

Power is supplied to the automatic drug solution injecting means 100 through the battery 150 and power is supplied to the foot switch 200 through the power source unit 206. The display unit 144 is connected to the automatic drug solution injecting means 100 And the state information of the display unit.

Accordingly, the user can check the state information displayed on the display unit 144 and know the currently set amount of the chemical solution injected, the injection rate, and the operation mode.

At this time, if the set amount of the injected chemical liquid, the injection rate, and the operation mode are to be changed, the user can set the operation mode including the desired chemical fluid injection amount and the injection speed by pressing the setting button 142. [

When the foot switch 200 is pressed in the state where the operation mode is set and the holding button 146 is kept in the off state, And the control unit 140 operates the syringe driving unit 130 in accordance with the set amount of the chemical liquid and the infusion rate according to the operation signal transmitted to the first communication unit 141 , And the piston 126 is moved forward by the operation of the syringe drive unit 130.

In other words, when an operation signal is input from the foot switch 200, the syringe pressurizing unit 132 pressurizes the syringe 120 such that the needle 122 of the syringe 120 is injected under the subject, The piston pushing unit 134 presses the piston 126 so that the chemical solution filled in the ampule 124 is injected into the body of the subject by the set injection amount and the injection speed.

The used syringe 120 is separated from the case 110 and then discarded and the new syringe 120 is inserted into the case 110 And repeats the above-described operation.

On the other hand, when the user changes the holding button 146 provided in the automatic drug solution injecting means 100 from the off state to the on state, the operation signal generated by the foot switch 200 is transmitted to the automatic drug solution injecting means 100 Only the operation signal generated by the operation button 145 is transmitted to the automatic drug solution injecting means 100 so that the automatic drug solution injecting means 100 injects the drug solution into the automatic drug solution injecting means 100 according to the operation signal input from the operation button 145 Operating method.

When the operation signal input from the foot switch 200 and the operation signal input from the operation button 145 are both received due to the failure of the holding button 146, The error information is displayed on the display unit 144 and the operation of the syringe driving unit 130 is stopped.

The automatic drug solution injecting apparatus according to the embodiment of the present invention is provided with the syringe driving unit 130 driven by the battery 150 in the small case 110 and the syringe 120 As the piston 126 of the automatic drug solution injecting means 100 is linearly moved back and forth, the chemical solution can be automatically injected at the chemical solution injection amount and the injection speed set by the user, and the operation of the automatic chemical solution injecting means 100 can be controlled using the foot switch 200 Therefore, it is possible to prevent damage to the treatment site due to the hand movement when the chemical liquid is injected.
